préface

OIN (Organisation internationale de normalisation) est une alliance mondiale d'organismes de normalisation nationaux (Comités membres de l'ISO). L'élaboration de normes internationales est généralement réalisée par l'intermédiaire de comités techniques ISO.. Chaque institution membre intéressée par un sujet pour lequel un comité technique a été créé a le droit d'être représentée au sein de ce comité.. Les organisations internationales gouvernementales et non gouvernementales en liaison avec l'ISO sont également impliquées dans ces travaux.. L'ISO travaille en étroite collaboration avec la Commission électrotechnique internationale (CEI) sur toutes les questions de normalisation électrotechnique.

Les projets de normes internationales adoptés par le Comité technique seront distribués aux comités membres pour vote.. La publication en tant que norme internationale nécessite l'approbation d'au moins 75% des comités membres.

Norme internationale ISO 11798 a été développé par le comité technique ISO/TC 46, Informations et documentations, Sous-comité SC 10, Physical Preservation of Documents.

Annexes A and B form an integral part of this international standard. Annex C is for reference only.

OIN 11798-1999 Informations et documentations – Persistance et durabilité de l'écriture, impression et copie sur papier – Exigences et méthodes de test

introduire
Writing materials and devices that meet the requirements of this international standard may be used to prepare paper documents with stable and durable images, c'est à dire. images that may have little or no variation in characteristics affecting readability, and the possibility of copying or converting paper documents into other data carriers, such as microforms.

It is primarily used for writing, impression, and copying on writing and printing paper as well as copying paper.

This standard specifies the requirements and test methods for assessing image stability. Certain properties of the image, such as wear resistance, depend on the combination of the image and the paper. Permanent files (OIN 9706) and archival files (OIN 11108) used to prepare files can differ greatly in attributes that are important for image quality and persistence. The test conditions of this standard are selected in order to obtain results representative of the majority of papers on the market for a particular imaging process.

Dans cette norme, the requirements are based on

— image color intensity and appearance;

— light resistance;

– imperméable;

– transmission of recorded images;

— résistance à l'usure;

— résistance à la chaleur;

– Record the influence on the mechanical strength of the paper.

More stringent limits and other requirements than those set out in this international standard may be required when testing materials and machinery for documents of the highest durability and durability.

Experience has shown that images written with India ink, as well as printed images using commercial printing inks, are highly durable. Cependant, in many documents, acid inks have affected the paper to the point of paper corrosion, and images produced by dry or liquid toner are also susceptible to aging problems.

The experience of modern images is limited to a few decades. Images prepared with modern materials and machinery are often completely different from older images in terms of composition and properties. Donc, conclusions based on studies of older documents in libraries and archives are of limited use when discussing the persistence of modern documents.

Strictly speaking, the only way to test the persistence of an image is to process the document and store it under relevant conditions for a long time, perhaps hundreds of years. En pratique, one must rely on observations of documents that are only a few years old, and an assessment of the impact of factors known to affect the persistence and persistence of images.

1 gamme
This standard sets out requirements and test methods for assessing the persistence and durability of writing, printing and copying on paper stored for long periods in libraries, archives and other protected environments.

It is applicable to

— Images on paper, except for documents within the ISO/TC 42 “photography” gamme;

— Colorful images.

The information content of a color image should be preserved, but not necessarily the full artistic quality of the color image. Files whose information content is subject to minor colour changes are not covered by this standard.

It doesn’t apply to

– Documents stored under harmful conditions, such as the effects of high humidity, overheating, radiation (comme la lumière), high concentrations of contaminants, or water that may promote microbial attack. Cependant, because files may be kept in an unprotected environment before being transferred to a protected environment, water and light resistance are important;

– Legal documents, such as bank documents, where authenticity is a major concern.

3 Définition
For the purposes of this standard, the following definitions apply:

3.1

copie

To produce an image on paper that is a replica of an image on another document carrier, for example by a photographic or electrostatic printing process

3.2

Official document

Recorded information that can be treated as a unit in the documentation process

[Source: OIN 5127-1:19,836)]

3.3

durabilité

The ability to resist the effects of wear in a performance situation

3.4

image

Pigments are distributed on paper as characters or other visually recognizable patterns

3.5

Monochrome image

A color record of the image

3.6

Colorful image

Consists of images recorded in a variety of colors, where colors form part of the information content

3.7

It can maintain chemical and physical stability for a long time

3.8

Permanent image

Images that have little or no change in properties affecting their use during long-term storage in libraries, archives, and other protected environments.
